The chemical properties of copper are stable, and the characteristics of cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance (the melting point of copper is as high as 1083 degrees Celsius) are integrated in one, so the copper connector is durable and can be used in different environments for a long time. The electrical and thermal conductivity of copper is second only to silver, and is widely used in the production of conductors, so Amass LC series connectors use silver plated layer on the basis of copper conductors, aiming to improve the current carrying performance of high-current connectors and ensure the efficient operation of intelligent devices.
